HOLDING AND PRINTING MECHANISM FOR WRAPP NG PAPER AND oTHER RoLLs.

Application filed November 3, 1925, Serial No. 66,452, and in AustraliaAugust 15, 1-925.

This invention relates to mechanism whereby the web of a roll of sheetmaterial, such as wrapping paper used in shops, will be printed upon asit is being withdrawn 5 from the roll. Advertisements and/or othernotifications may thus be put on the wrappers before the latter are madeto enclose goods.

Our improvements relate to the machine frame and .to the inking andprinting mecha-,

nisms. The frame'carries all the parts conveniently, each of variousrollers of this machine being easily changeable for another. The inkwill not leak from its reservoir, and

frequent renewal of ink will not be required.

- The colour or colours of ink can be varied.

Our machine will operate as a counter. adjunct, and allow of easilydrawing out the paper and tearing it off, leaving an edge of paper readyfor grasping when the next withdrawal occurs. 'Any desired length of.paper may be drawn from a roll in contact with the printing roller orrollers, before I severing. The severing need not be for wrappingpurposes; as paper is, when printed'on suitably, often of use to make awin-. dow frieze,- or background, or for other purposes. I a

Construction according to this invention is herewith illustrated, butdetails may be modified while retaining any combination hereinafterclaimed.

In the drawings, Figure 1 is a tional view of the machine.

Figure 2- is a front view partly in section of the machine equipped withtwo rolls of paper, and with an inking and printing device for eachroll.

Figure 3 is a side sectional view of part 40 of Figure 1, but set in adifferent position, which will permit of removal of the print-. ingroller, or if desired the said roller and parts under it. I

Figure 4 is a perspective view of part of 4 the inking mechanism.

The machine has a main frame formed by cheeks 1, 1*, connected andspaced apart by bars of'which three, 2, 2",2 are shown,

either cheek being removable, by unscrewing the end fastenings which areshown as nuts 2 on the said bars. This frame has feet which are adaptedto rest and stand firmly on glass or other polished surfaces,

side secagainst a cheek.

and also adapted to allow the machine to be slid into'other positionswithoutdamaging the glass or other supporting surface..- Thus on theunderslde'of each foot is a pad 1, which may be of rubber.

At an upper front part of the machine, that is facing the operator eachcheek has a bearing, the entrance to which is aslot'l, I

Figure 1, carrying the end of a removable spindle 3, herein called. themain" spindle,

which carries the paper roll or rolls.

We show two rolls 4, 4?, and to align these with their printing'mechanismswe provide shdable means of-suitable form, shown as members 5and 6. Thus. the member 5 has apertures throughwhich extend the spindle3, and the bars 2', 2, 2 Through the member 6' which is small, only thespindle3extends. Member. 5' and member 6- will be each set abuttingagainst a roll of paper, as

in Figure 2, to prevent the latter sliding out,

of printing alignment; but members 5, 6,

may if desired be. set at either side of the side abutting mainframe,'or on'e at each When only .one vp aper'roll in use, but

needs. to be prevented from sliding, one alignment member will suflice,either. a plate 5 or a member-6. The.plate-5 is shown abutting againstthe tone, and the member removed or not. Plate. 5 has a perforated V lug5 carrying a set screw 5 extending 6 against .the'roll 4, keeping thesepaper rolls in alignmentwiththeir' printing roll- Plate 5 has thefurtheradvantage that, when a cheek is removed it will retainthe through theperforation togrip the spindle;

member 6 has also adjustment means shown as a p1n3 lnserted m a vhole 1nthe .SPlIlCllB, which has sufficlent holes for selection pur' poses.

. We provide at the frame rear a trough or troughs 8, two being showninFigure 2. These are slidably supported 'onthe bars 2,

2 which .are parallel. This trough has at its lower part means, shown aseyes 8*, engaging the bar 2, and has at its upper part means, shown as-aclip 8? which frictionally grips the upper bar 2*,but is detachabletherefrom by hand pressure, .Ontl'etaching the clip as in Figure 3, thetrough top will swing rearward, and thus permit an attendant to haveeasy access to the trough contents. e find it to be convenient to makethe trough with cast metal ends 8, each carrying an aforesaid 'eyc"8',"the walls and'base of the trough being ""of' s'heet"'1 ne'tal securedto "the ends, the front wall being provided with the said clip 8" whichmay be integral.

The trough base is its ink-containing part, and meansare provided tolimit the amount of ink therein. Thus a passage 9 having anescape'opening e r-is shown at a suitable level- Thisiopening andpassage (the taper the-latter"beingshown wide) are usable for 1replenishing the ink. 9 'indicatesra" closing Above the ink well at thetrough base, the trough conta'i-ns 'in'k distributing. means.

' Above the or each printing" roller is an abutment roller 1.7 which isin one'picce or is formed in sections, so that any sectioir can beindependently rotated: This roller has a spindle 17 supported inbearings 17? in cheeks 1, 1

As the mechanism which is located below the abutment" roller is subjectto the'upward. pressure of the springs'12 and14, thesaid mechanism risesas high as :the abutment roller allows; and as the paper from'the;

source provided as the roll is made-to pass between the abutment rollerand the print ing roller, the paper willitherefore become printed onby'the contacting roller? as the paper'is moved along.

In practice the paper is drawn out, as shown in Figure" 1 by brokenlines, from the roll and is'passedv under-the abutment roller, thenabove the latter, and then to a guide which is provided, shown 'as a'roller' 18, over which the paper isdrawn pastfihe edge of ablade19,'termed the tearing-blade. This blade is-supportedat the frontofthe'top frame which has suitable pivotal -supports such as thebearingso'f-the abutment roller 17;. This top frame can" be easilygrasped by being swung upward, as per the,

arrow in" Figure 1; This "top frame""con'- sists of the parts 18, 19,and 20. It'eXtends' above,- and is supported iat'its front by the You ofP p n mally; but whenraised by swinging'it as per arrow A, it'ismovedclear of the paper roll which" can then be changed. 'This top framecarries paper retaining clips 21 above guide roller-18,' to press on:the paperand keep it in aligrr ment, the clips holding the paper"against 120 the said roller.

As'the roller 18, which rests on the paper roll, is easily rotatableby'f1TlCtlOI1,jl3h61l11- rolling of the papeifrequired from time to timewill not be materially impeded; '"A tearing blade'19 of any suitabledetail, as,
